Chapter 1, Problem 7STP

To determine

The correct option to be chosen.

Answer to Problem 7STP

The correct option is (A).

Explanation of Solution

Given:

The following bar graph is given for the densities of oil, water, corn syrup and orange juice. Density is plotted along y -axis and the type of liquids along x -axis. The density of oil is 0.9 g/mL.

  

Formula used:

The expression for conversion of g/mL to mg/cm³ is,

  $1\text{ g/mL}=1000{\text{ mg/cm}}^{\text{3}}$....................(1)

Calculation:

Substitute 0.9 g/mL for 1g/mL in equation (1),

  $\begin{array}{l}\text{0}\text{.9 g/mL}=0.9\times 1000{\text{ mg/cm}}^{\text{3}}\\ \boxed{\text{0}\text{.9 g/mL}=900{\text{ mg/cm}}^{\text{3}}}\end{array}$

Conclusion:

Hence, the correct option is (A) $900{\text{ mg/cm}}^{\text{3}}$ .
